BOSTON — The Bruins have yet to get a 5-on-5 goal from their top line in this second-round series with the Canadiens, but coach Claude Julien is confident his KIL line will get its act together soon.

The unit of David Krejci, Jarome Iginla and Milan Lucic combined for just three attempted shots in the first two periods of Thursday's 1-0 overtime win in Game 4. They were chasing the game much of the night, and all had a Corsi-for percentage under 50.

With Game 5 on Saturday in a 2-2 series, the Bruins need them to get going soon.

“They've just got to find their rhythm again,” Julien said after Friday's optional practice. “They're working hard. It's just a matter of time here. Certainly we've seen them at their best and a little bit of adversity is what they're facing right now, but they've been as steady as we could've asked this year. Just a little bit of time and they'll find their groove again.”

Krejci has no goals and three assists in nine playoff games, well below the expected pace of the two-time playoff scoring champion. Iginla had three goals and two assists, but his Game 3 6-on-5 goal is his only point in the second round. Lucic had a goal and two assists in the first three games of the series, including an empty-netter to clinch the Game 2 comeback win, but went scoreless Thursday.

The Bruins have essentially had just two scoring lines in the series, the ones centered by Brad Marchand and Carl Soderberg. Call-up Matt Fraser potted the only goal Thursday with an ugly overtime goal.

Lucic was the only one of the three to practice Friday. It was an optional practice, with most of the team's heavy minutes players staying off the ice, some choosing to play hallway soccer. The only other top-nine forward to skate was Carl Soderberg.
